Magnetic exchange force microscopy from first principles: application to the antiferromagnetic NiO(001) surface

New Journal of Physics, 2014
We present an accurate ab initio description of the magnetic exchange force microscopy (MExFM). As a prototypical system, the antiferromagnetic NiO(001) surface probed with a Fe tip is investigated. The tip–surface interaction is described on two levels.
